UWB Double Ridge Waveguide Coupler with Low Loss
A new ultra-wide band coupler obtained with two crossed double-ridge waveguides coupled through one aperture is proposed. The main features of the coupler include: operating frequency from 6 GHz to 18 GHz; coupling coefficient ...
Reconfigurable Dual Band Bidirectional ReflectionAmplifier with Applications in Van Atta Array
We designed a reconfigurable dual band reflection amplifier with operation frequency bands over 1.8 GHz and/or 2.4 GHz. This one-port amplifier boosts the reflected signal over either of these two ...
A Full-duplex Bidirectional Amplifier with Low DCPower Consumption Using Tunnel Diodes
A low-power, switchless, full-duplex bidirectionalamplifier operating in the 915 MHz (ISM band) is proposed.It is composed of two identical reflection amplifiers and one90◦,−3dB Branch Line ...
